@ibarra23 Well I'm glad you told me it was a dog, because I never would have guessed that

I would suggest you start with some simple shapes, circles are a good choice as you'll see immediately if they are connecting (start to end) or not, and then you can repeat the same job again and see if it matches or is shifting.

These tests will tell you if it's a backlash (belt) issue, motors losing steps (current or friction) issue or something else.

I don't know what parameters you can change in EleksCAM but if you slow the machine down (feed rate) does it improve? Steppers have higher torque at slower speeds so if it's current or friction it may look correct or at least closer if this is the case.

@leunam4 The default start position is lower left, you can select center or other corners from the settings menu. You can also use the simulation "view" to see where it aligns (shown as an orange dot and 0,0 marking) and there's also the engrave or trace frame features to show you the work areas with the laser head.

You need to post a picture of how the laser is wired to the controller.

In the custom firmware menu upload 1.1e Non-PWM.

If the board is an old design (Grbl 0.8) this firmware will make the laser output work, the downsides are it will only work with my T2Laser as I do some internal "tricks" to make it work and you won't have any laser power control simply because the board isn't wired correctly for it.

The bypass method I described in a previous post would allow you to get power control but T2Laser has other modes that will achieve the same thing so it's not necessary.

Hi Zax, I have downloaded your prog, it seems good will contact you later if I decide to use it, but right now am happy it's working after such a long time trying to sort it out the ElkesCam prog is working at the moment and i'm scared stiff of upsetting the damn machine in case it throws a wobbly and stops again he he
but thanks again for all your help.
regards Tug

Thanks a lot for your answer but I don't really understand how I can change these parameters, is there any tool to inject them ?

I don't really want to change the parameters Easel is doing it itself and when I put back the laser everything is changed... I don't really know what easy to use software I can use for the drilling part
